Phenylacetylene(CAS#536-74-3) yazisa
umgangatho
I-Phenacetylene yi-organic compound. Nazi ezinye zeempawu zephenylacetylene:
1. Iimpawu ezibonakalayo: I-Phenacetylene iyilwelo olungenambala oluguquguqukayo kwiqondo lokushisa.
2. Iimpawu zeMichiza: I-Phenylacetylene inokusabela ezininzi ezinxulumene ne-carbon-carbon triple bonds. Inokuthi ingene kwi-reaction eyongeziweyo kunye nee-halogens, ezifana nokuphendula okongeziweyo kunye neklorini ukwenza i-phenylacetylene dichloride. I-Phenacetylene inokuphinda ifumane ukusabela kokunciphisa, iphendule nge-hydrogen phambi kwe-catalyst yokwenza i-styrene. I-Phenylacetylene inokuphinda iqhube i-reagents endaweni ye-ammonia ukuvelisa iimveliso ezihambelanayo endaweni.
3. Ukuzinza: I-carbon-carbon triple bond ye-phenylacetylene yenza ukuba ibe neqondo eliphezulu lokungahlambuluki. Ayizinzanga ngokwentelekiso kwaye idla ngokuzenzekela kwiziphumo zepolymerization. I-Phenacetylene nayo inokutsha kakhulu kwaye kufuneka igwenywe ekudibaneni nee-oxidizing agents ezinamandla kunye nemithombo yokutshisa.
Ezi zezinye zeepropathi ezisisiseko ze-phenylacetylene, ezinexabiso elibalulekileyo lesicelo kwi-organic synthesis, isayensi yezinto kunye nezinye iinkalo.
Ulwazi ngoKhuseleko
Phenacetylene. Nalu ulwazi lokhuseleko malunga nephenylacetylene:
1. Ubutyhefu: I-Phenylacetylene inobuthi obuthile kwaye inokungena emzimbeni womntu ngokuphefumla, ukudibana nolusu, okanye ukungeniswa. Ukubonakaliswa kwexesha elide okanye eliphezulu kunokuba nemiphumo emibi kukuphefumula, inkqubo ye-nervous, kunye nesibindi.
2. Ukudubula komlilo: I-Phenylacetylene yinto enokutsha ekwazi ukwenza umxube oqhumayo kunye ne-oxygen emoyeni. Ukuvezwa kumadangatye avulekileyo, amaqondo obushushu aphezulu, okanye imithombo yokutshisa kunokukhokelela kumlilo okanye ugqabhuko-dubulo. Ukudibana nezinto ezinjengee-oxidants kunye neeasidi ezinamandla kufuneka kuphetshwe.
3. Kuphephe ukuphefumla: I-Phenylacetylene inevumba elibi elinokubangela isiyezi, ukozela, kunye nokungakhululeki kokuphefumla. Ukungena komoya okulungileyo kufuneka kugcinwe ngexesha lokusebenza kunye nokuphefumla ngokuthe ngqo kwe-phenylacetylene vapors okanye iigesi kufuneka kugwenywe.
4. Ukukhuselwa koqhagamshelwano: Xa uphethe i-phenylacetylene, gqoka iiglavu ezikhuselayo, izibuko kunye nempahla efanelekileyo yokukhusela ukuphepha ukudibanisa nolusu kunye namehlo.
5. Ukugcinwa kunye nokuphatha: I-Phenylacetylene kufuneka igcinwe kwindawo epholileyo, enomoya, kude nemithombo yomlilo kunye namadangatye avulekileyo. Isingxobo kufuneka sihlolwe ukuba sikwimeko entle na phambi kokuba sisetyenziswe. Inkqubo yokuphatha kufuneka ilandele iinkqubo zokusebenza ezikhuselekileyo ukuphepha iintlantsi kunye neentlawulo ze-electrostatic.
Ukusetyenziswa kunye neendlela zokudibanisa
I-Phenacetylene yi-organic compound. Yenziwe ngeringi ye-benzene edityaniswe neqela le-acetylene (EtC≡CH).
I-Phenacetylene inoluhlu olubanzi lwezicelo kwi-organic synthesis. Nazi ezinye zezona zinto zisetyenziswayo:
I-Pesticide synthesis: i-phenylacetylene yinto ebalulekileyo ephakathi ekudityanisweni kwezinye izibulali-zinambuzane ezisetyenziswa ngokuqhelekileyo, ezifana ne-dichlor.
Ukusetyenziswa kwe-Optical: I-Phenylacetylene ingasetyenziswa kwi-photopolymerization reactions, njengokulungiswa kwezinto ze-photochromic, izinto ze-photoresistive, kunye nezixhobo ze-photoluminescent.
Iindlela zokudityaniswa kwephenylacetylene kwiilabhoratri nakwimizi-mveliso zezi zilandelayo:
Ukusabela kwe-acetylene: ngokusebenzisa i-arylation reaction kunye ne-acetylenylation reaction yeringi ye-benzene, iringi ye-benzene kunye neqela le-acetylene zidityanisiwe ukulungiselela i-phenylacetylene.
I-Enol rearrangement reaction: I-enol ekwiringi ye-benzene idibene ne-acetylenol, kwaye i-rearrangement reaction yenzeke ukuvelisa i-phenylacetylene.
I-alkylation reaction: Iringi ye-benzene ifakwe
